Abstract

Abstract

Sandstone type uranium deposits in Erlian Basin are concentrated in the Ba-Sai-Qi ancient channel. The northern part of the channel is mostly covered by basalt, which increases the difficulty of uranium exploration. According to the electrical characteristics of the basalt-covered area, the audio frequency magnetotelluric survey (AMT) was optimized and carried out to obtain uranium metallogenic information such as fracture, sand body, basalt distribution, basement, and tectonic framework, providing deep electrical data support for evaluating the prospecting prospect in the area. There are ternary electrical structures-basalt cap, sedimentary strata and basement rock in basalt-covered area. The sand bodies and fractures of Saihan Formation favorable for uranium mineralization are well developed in the area, and the deep thermal fluid can provide heat source for uranium superimposed mineralization. Uranium accumulation in sedimentary strata near basalt caprock should be considered in uranium exploration, and also uranium source conditions. Therefore, it is suggested to find out the NNW-trending fracture distribution in the west of basalt-covered area so as to provide a basis for uranium exploration of hydrothermal superimposed mineralization.
